DONALD, Prancnn. An'nnnsou, and JAMEs ORILEY, citizens of the UnitedStates, re-

5 siding at. Havrc, in the. county of Chouteau and State. of Montana,have. invented certain I (new and. useful Improvements'in Ditchin'Machines, of which thefollowing is a speci- 1o Our invention hasrelation to new and useful improvements in ditching machines and has asone of its o .jects to. improve the construction of this classofmachine, which excavatesthe dirt. and. discharges it at one of itssidesf This machine may run on a'track and'over.

the ditch that is mg dug, and thus the exc'avation isfbetween 1th earthon each sideicf the ditch, wherecn runs the rails, solid; oi itmay bemounted on ordinary wheels, as shown, and, may be self propelling or itmay be meved about by anm al ower, or both.

Anot er and the main'object of our in 2'5vnt1on Is to provide means bywhich the conveying erg is adjusted so as to give said conveying ar asweep from a vertlcal position, too position where the outer end of theaforesaid \conveyerarniis abovdtthe ground,

the in thine j everMtime the same is moved forwarf, and rtherniore itispointed out that the width of the ditch depends directly on thewidth of.tlwbuckets andthe said buckets may be at detached and others of desiredwidth placed in their-stead.

1,"; W; these and other objects in view our \Lnventmn consists. of thenovel construction a nd arrangement of parts as are hez einafter .40described in the following specification and polnitel out in the claimshereunto appen e a f 1 Reference being had. to the drawings,-

a'chme showing conveying arm in ground, and further showing source ofowcr foroper- ,gtlngsame. Fig. 2, is aside e ovation of our I invent onshowing 1 generalarrangement of conveying arm, Windlass, and drivingengine. .Fig. 3, is a rear elevational view, showin clearly, wheels andcables used in adjusting e rails, leaving the I :each of the front andrear uprights of said vertical 'veying pulley 11, over jform a part ofthis specification:--F1g-' 15 ur 1 1s afront elevation of our ditchingan ings, the supportlng frame 1, is mounted on.

e ordinary manneni the; wheels 2, in th .e aforementioned lockingdevice. a detail view of the. outer end of Power is furnished by meansof a steam engine 3, which may usual types.

This engine is mounted very near the front end of the supporting frame.

Mounted on th e .-said suplilorting frame 1,

and substantially secured t ereto by means of braces 4, are verticalframes 5 and 6, one midway between the central portion and ends of saidsu porting frame. Mounted and keyed to t e Shaft 7, of said frontvertical frame5, is a-pulley 8, over which runs the belt 9, of the drlveWheel 10, of said engine. Also mounted securely on said shaft 7, betweenthe veyng belt 12, to which is secured the buckets 13, by anysubstantial and well frame 5, is the con. which runs the conbe of anyone of the,

own means. The conveying arm 14, is

bifurcated 10h fit loosely over said shaft 7. The outer arm is recessedforming two smaller arms 16, having eyes 17, wherein isrnounted aspindle 18, to which issecured a roller 19, overwhich rolls saidconveying belt 12, of sald conveying arm -14. The most horizontalposition of the conveying arm necessar is shown by the dotted lines inFig. 2; the deepest possible cut is being made when the said arm is in,a vertical Secured near the central portion conveyer arm, and on eitherside thereof are rockers 20, having fastening means 21, for the ends ofthe cable 22. One end of said of said runs over the spool 25, whichrotates on at its upper end, forming per forated arms 15, w

end of said conveying position.

g .cable 22, is fastened .securely at 23, then if frame at 36 theupright arm 37, is secured to spindle 26, of said supporting frame. Seidl cable then entwines around the spindle 27, several turns being made,thence upward and over the spool 28, which is mounted on the spindle 29,of said upright frame 6. The said cable then runs in an inclineddownwardly direction, the other end secured to the rocker at 29. As thecable on each side of the Windlass works similarly, we deem it necessaryto explain the operation .of one only.

When it is desired to elevate the conveying arm the handwheel 30, isrotated. forwardly;- thus spindle 27, also rotates, as said wheel 30, iskeyed thereto; the result being that said cable 22, is drawn over saidspool 28 and wound around spindle 27, thus elevating the conveying armto any desired position. That part of said cable that already entwinedaround said spindle 27, is paid out and rolls over spool 25, passinginto the groove 81, cut in rocker 20. When it is desired to lower saidconveying arm the wheel is rotated in a reverse direction and thereverse action of the cable and the conveying' arm is the result. Whensaid conveyer srm is in the desired. position the spring actuated. pin32, (Fig. 6) is fillO. ed to engage the sprocket wheel 33, mounted andkeyed to the outer projecting end 34, of said spindle 27. Said pin isactuated by a lever 35, which is pivoted to said supporting said levernear its center and has at its upper end an eye 38, wherein the lowerend of said pin is pivoted. The spring 39, holds the pin in engagementwith said: sprocket wheel 33, normally; so when it is desired to turnthesaid wheel the pin is disengaged by pressing the foot on thefoot-restAO, of said unlocking lever. This stretches the spring and whenthe conveying arm is at the desired angle the foot is removed and saidspring actuated pin 32, shoots back again into engagement with saidsprocket wheel. It is obvious that the locking mechanism may be oncit-lien side of the machine, or both.

So that our machine may be adjusted and maintained in a level position,jacks 41, are supplied at the rear end directly over the rear axle forthis purpose.

Secured to the front side of the uprights'of the vertical frame 5, is achute 42, wherein the dirt is dumped from the buckets 13, and is shotoii to the side of the machine. This chute may be arranged on eitherside of the machine, or bOlill.

Though we have specifically described our invention we claim the rightto make such l alterations and changes in its construction andarrangcmentas will be within the scope and 5 not depart from the spiritof our invention and which will be obviously necessary in itsmanufacture.
